Description

FIELD OF THE INVENTION [0001] The present invention relates to a ship navigation system,

More particularly, the present invention relates to a system and method for navigating a vessel and a baseline based on static information such as sharpness, call sign, and MMSI acquired from an AIS (Automatic Identification System) And a system and method for displaying on the map only the wake of ships that have passed through a specific zone and a reference line already created on a map by querying stored vessel information will be.

Generally, a ship is a means of transportation for transporting large quantities of cargo or passengers from sea or for fishing, and an engine room and a crew room are provided inside the hull.

These vessels are subject to rapid response to such maritime accidents due to the high risk of collision with the hulls on the reefs, collisions between vessels, ship sinking or damage due to typhoons, etc. Do.

On the other hand, as the number of ships existing within the control area of the coastal area of the coastal area has increased recently, it is difficult for the controller to individually monitor and control all the vessels in the control area.

In this regard, Registration No. 10-1313264 has been proposed as a prior art. The present invention relates to a method and system for identifying suspicious vessels by analyzing a ship 's operation pattern tracked by a multi - sensor, and more particularly, to an automatic identification apparatus mounted on a ship in operation at sea; Radar and automatic identification devices mounted on coastal base stations and surveillance vessels / ships so that the ship can be monitored on the coast or surveillance ship; The analysis server of the control center compares and analyzes the ship information including the position information of the ship identified / received from the radar or the AIS from the coastal base station or the surveillance vessel / ship, and the position information of the ship received from the control center And a control console based on an electronic chart, which can be displayed as a target on the screen.

However, the above-mentioned registered patent automatically checks and monitors whether the ship is operating according to the designated route and time schedule, and judges whether it is a suspicious ship such as smuggling or the like, and the controller arbitrarily selects a zone or a baseline, There is no function of extracting only information about the ship which has passed the baseline. Furthermore, the patent is intended to automatically identify suspect vessels and their use is extremely limited.

In particular, in the past, when an incident such as a ship accident occurred in the offshore waters, it is very important for accident analysis of surrounding vessels in the relevant area, but it is impossible to set up the inquiry condition. It is still a burden to the controller's work due to the use of the method of extracting the snapshot data from the database using information such as sharpness of the chuck, MMSI, call sign, and the like.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a marine traffic control center that grasps accurate flight information based on time, And to provide a zone and baseline-based navigation vessel inspection system and method that can help in efficient control.

In order to solve such a technical problem,

At this time, in the third step, the monitoring equipment displays the wake-up information of the ship crossing the reference line on the chart with the reference line.

According to the present invention, when the ship data is fetched from the database by information such as sharpness, MMSI, call sign, and the like of the existing ship, Since many inquiries are made simultaneously on many vessels that pass through the area, there is a great advantage in terms of user convenience and efficiency as compared with a method of inquiring one vessel by ship. Therefore, the controller of the control center can make reasonable and efficient decision making when monitoring and controlling the ship.

In particular, when the occurrence of an incident such as a ship accident occurs in a sea area, the present invention often requires the information about the surrounding vessels in the relevant area. Therefore, when a comprehensive search of the ship is required, If it is necessary to identify the status of vessels that are effective in accident analysis and crossing certain boundaries, it is also useful for effective maritime control by enabling quick and precise status monitoring through baseline-based vessel check function.

In addition, according to the present invention, it is possible to utilize various aspects such as obtaining information about major vessels that mainly pass through the route through the inquiry of a vessel passing through a specific zone or a baseline, or acquiring information of the surrounding vessels about a vessel accident area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. It is to be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but on the contrary, is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

1, the area and baseline-based vessel inspection system according to the present invention stores AIS information transmitted from an AIS (Automatic Identification System) transmitter 10 mounted on a ship 1 in a database in a maritime traffic control center And the stored vessel information is searched to display only the wake of the ship which has already passed through the specific zone and baseline generated on the sea chart.

At this time, the AIS (Automatic Identification System) is an apparatus for providing navigation information in real time such as position, speed, and speed of a ship, and is an automatic ship identification device for preventing a ship from colliding at sea.

Vessel Traffic Service (VTS) is a system that detects the position of a ship (1) such as a radar, a VHF equipment such as a microwave radio communication equipment, and an automatic identification device (AIS) And to provide navigation safety information. The tasks of maritime traffic control are mainly the risk of departure from route, access to dangerous area, collision of ships and so on. To provide information on the prevention of marine casualties, to provide advice and instructions, to adjust the priority of the port of entry and departure to improve the efficiency of the port operation, and to provide port operation information such as berths, marinas, Provide navigation safety information for safe operation of ships such as maritime firing, quick initial action and propagation in case of marine accidents and emergencies.

The navigation system 100 is a system operated by a maritime traffic control center. The navigation system 100 includes an AIS receiver 20 for receiving AIS information of the ship 1, The AIS information of the ship received by the equipment 20 is stored in the database 32 and the AIS information of the ship of the database 32 is inquired according to the inquiry condition regarding the specific zone and the reference line to extract the ship inquiry information When the control server 30 and the user such as the controller enter the inquiry condition regarding the specific zone and the reference line for the inquiry of the ship, the inquiry server 30 generates and transmits the inquiry request information to the control server 30, And a monitoring device 40 for receiving and outputting the navigation inquiry information of the ship extracted according to the inquiry condition of the navigation request information.

At this time, the monitoring equipment 40 inputs the navigation request information about the period and the specific zone or the reference line for which the user wants to inquire the ship by the controller or the like, and transmits the navigation request information to the control server 30, The ship's wake information is displayed, but only the wake of the ship that has passed the specified zone and baseline already generated on the chart is displayed.

Hereinafter, the structure of the present invention will be described in more detail.

First, the AIS receiving equipment 20 of the VTS Center receives AIS information in real time from the AIS transmitting equipment 10 installed on the ship 10.

The AIS information includes the name of the ship, the calling code, the MMSI, and the like as static information of the ship, and includes latitude, longitude, incline, bow direction and the like as dynamic information.

The control server 30 collects the AIS information of the ship from the ship 1 equipped with the AIS transmission equipment 10 while navigating in the control area from the AIS receiver 20 in real time, The information is cumulatively registered in the database 32 in time chronological order.

At this time, it is preferable that the AIS information of the ship registered and stored in the database 32 accumulates and registers the AIS information of each ship for several months to several years.

The control server 30 can search the AIS information of the ship of the database 32 according to the inquiry condition of the navigation request information received from the monitoring equipment 40 and extract the navigation inquiry information of the ship.

In particular, the control server 30 can minimize the data to be inspected by the controller by inquiring the controller of the control center on the movement trends and suspicious vessels of the nearby vessels in accordance with the specific zone and baseline conditions when the wake of a specific vessel or an accident occurs The tracking request information including the inquiry condition is received from the monitoring equipment 40.

That is, when the navigation request information including the inquiry condition including the specific zone, the reference line, the period, and the like is received from the monitoring equipment 40, the control server 30 searches the AIS information of the ship of the database 32 according to the inquiry condition And extracts the navigation inquiry information. In this case, the inquiry condition requires a specific zone and a baseline, and can specify the period and the vessel. For example, you can search for vessels that have passed a specific zone or baseline between 20 August 2015 and 20 September 2015 at the same time, or if a particular vessel has passed a certain zone or baseline during that period And generates navigation inquiry information of the ship to be transmitted to the monitoring equipment 40. [

Such inquiry condition is input by the user in the monitoring equipment 40. When the controller inputs the inquiry condition regarding the specific zone and the reference line for inquiring the ship, it generates the inquiry request information and transmits it to the control server 30, Receives the navigation inquiry information of the ship extracted according to the inquiry condition from the control server 30, and outputs the navigation of the ships.

Of course, it is natural that the above-mentioned inquiry condition can be identified by specifying a period or a ship with a specific zone and a baseline as essential.

The monitoring device 40 may be a wired / wireless terminal connected to the control server 30 by a network and capable of inputting a display screen and a key.

The monitoring equipment 40 may be a facility inside the control center, a computer capable of a normal Internet connection, a smart device, or the like. Also, if the user needs log information in addition to the controller and has the access right to the control server 30, the inquiry service can be used through the monitoring device 40 connected by wire or wireless.

Hereinafter, a zone-based navigation vessel inquiry process according to the present invention will be described with reference to FIG. 2 and FIG.

A user such as a controller inputs a query condition for selecting a specific zone together with a period to be inquired through the monitoring equipment (40). Accordingly, the monitoring device 40 transmits the navigation request information including the input inquiry condition to the control server 30. (S10)

The control server 30 searches the AIS information of the ship registered in the database 32 according to the inquiry condition of the wake-up request information and inquires the wake-up T of the individual waters (S12)

After the step S12 is performed, it is determined whether or not the vessels pass through the selected zone A, and whether or not there is a vessel passing through the specific zone A is extracted (S14). At this time, Can be formed in various shapes such as a rectangle, a circle, and a polygon.

In this case, whether or not the trajectory T of the ship is included in the specific area A is determined by determining whether any point P of the trajectory T is inside or outside the graphic form of the specific area A Use mathematical formulas.

In particular, the control server 30 repeatedly calculates each of the plurality of traces (T) retrieved from the database 32 to determine whether or not the specific area A is included. If it is judged that the current target trajectory is within the specified zone (A), judge the remaining trajectories immediately, and repeat the operation for the next ship.

After the ship having passed through the specific zone A is extracted after the step S14 is performed, the entire navigation inquiry information of the extracted ship is generated and transmitted to the monitoring equipment 40 for display.

That is, if it is determined through the step S14 that the target trajectory is inside the graphic form, the corresponding vessel displays the entire trajectory of the ship so that the entire trajectory can be expressed on the chart because the selected vessel has passed through the selected region.

Next, a baseline-based navigation vessel inquiry process according to the present invention will be described with reference to FIGS. 4 and 5. FIG.

A user such as a controller inputs a query condition for selecting a reference line along with a desired period of time through the monitoring equipment 40. Accordingly, the monitoring device 40 transmits the navigation request information including the input inquiry condition to the control server 30. (S20)

Then, the control server 30 searches the AIS information of the ship registered in the database 32 according to the inquiry condition of the wake-up request information, and inquires the wake (T) of the individual waters. (S22)

After the step S22 is performed, it is determined whether or not the ship's trajectory T crosses the selected reference line L to extract whether there is a ship crossing the reference line L. (S24) At this time, L) may be formed in a line segment shape.

In this case, whether or not the ship crosses the reference line L is determined by using a mathematical formula for determining whether the ship's trajectory T intersects with the reference line L.

In particular, the control server 30 repeatedly calculates each of the plurality of traces (T) retrieved from the database 32 to determine whether the reference line L intersects. If it is judged that the current target trajectory intersects with the baseline (L) by repeatedly judging the condition of the wake of all the vessels, the judgment on the remaining wakes is immediately stopped and the repetitive operation is performed on the next vessel.

When the vessel crossing the baseline L is extracted after the step S24 is performed, the entire navigation inquiry information of the extracted vessel is generated and transmitted to the monitoring equipment 40 for display.

That is, if it is determined through the step S14 that the target trajectory intersects the reference line L, the ship expresses the entire trajectory of the ship so that it can express the entire trajectory on the chart because the vessel has passed through the selected region.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course it is possible.
